Electric pumps (ACMPs) for the hydraulic system automatically activate when which condition is met?

Explanation:
Switches set to AUTO control the automatic start/stop behavior of the electric hydraulic pumps. When the switch is in AUTO, the ACMPs come on automatically to provide hydraulic pressure as soon as the system detects a demand or pressure drop, and they shut off when pressure is adequate. If the switch is OFF or in MAN, the pumps won’t start automatically, even if hydraulic demand exists. Power availability from generators or an APU isn’t what triggers auto start by itself; the trigger is the switch position, which is why AUTO is the correct choice.
